Ok, I'll give it a try...
1. Model Setup:
* Constraints are correct. Since these are pinned supports, I don't think truss option is necessary.
* There are nodes floating not attached to elements. "Delete Unused Nodes". Try the Refine…
Tested a model similar to the one you show. Different formats attempted:
* Dxf: No good. Automesh 2D just blanket fills everything within the outer perimeter.
* STL: Success. All regions meshed.
* STEP: Success. All regions meshed.
…
For Move/Copy:
Is it possible to include two Mouse Pick buttons, similar to the other copy functions, so that nodes/elements can more easily be moved/copied from one point to another?
Try Solution / New stress and strain / Stress in element coordinates. Previous versions listed this with (beams, shells) after the description. Similarly, look under / New force and moment to activate your bending moment, shear, and axial force o…
@LHartley,
There's nothing like a good project to accelerate the learning curve. Apologies if the following post restates what you already know, but others learning the system may find it useful.
I noticed in the reactions.png file you posted…
@LHartley,
Helps to note Node Order in which elements are first created (eg: to make a mitered picture frame of angles from 4-pts. in a plane, pick nodes (a to b) for each element, say, counterclockwise).
"Invert" element and "Hide All but this" (…
If you have trouble getting going, here is that file in dxf format. I opened the download-stp file in FreeCAD, highlighted parts, then exported as dxf. In & out, without getting my feet wet.
Verify the scale of the tower. I didn't see anythi…
DesignSpark install note: had difficulty registering for required (free) account at end of install (~2 Gb). Had to go through website to register, then software let me in.
For those familiar with Sketchup, it has a similar feel at the outset.
OK. Yes, I was wondering why I thought it worked the first time (only).
Also, is it possible to make ALL the selected Sources translate perpendicular to the Target?
As it stands, like a fly swatter, unless the Target (swatter) is larger than the S…
@Sergio:
Ha! I was thinking "script suggestions" for better coding technique. I can see how it might sound I was offering to write more code.
Off the cuff, for wish 1) & 2) I'd say the cleanest file read would be from the Mecway generate…
Inspired by others to work on scripting skills. Made a couple modifications on (two) clever scripts previously posted by others above:
1) AnchorSkew (Thanks @Victor --Skew tool). Noticed the skewed mesh would wind up scaled off the display the fu…
@Victor: Yes, that can work. Creates possibilities for some other scripts in mind.
Thanks.
# Cloud of nodes stored previously in Named Range
# Hub is only active node in screen selection set. Might be part of Cloud.
# Re-assign selectio…
Playing with scripting lately.
Is there a way to suspend the execution of a Mecway script mid-way, so that user can mouse-select nodes/faces/elements when prompted?
Spider Beams tool. Draws Line2 elements from a center Hub (origin) to a selected cloud of nodes.
Transition easily from line elements to shells. Save your node budget for areas of interest. Hyper-stiff Spider Beams can approximate behavior of a…
That's a nice bit of analysis, disla. Could you shoot me a copy of your file? Did you say you used the RIGID card?
Well, I wanted to see what shapes other software would produce using RBE2 & RBE3 elements. Drug out the old Nastran stuff. Fel…
Thanks for the feedback.
To begin, employing an array of hyper-stiff beam elements, what I've called Spider Beams, is NOT the same as RBE2/RBE3 elements. Those elements use displacement constraint functions in ways I don't fully understand, and …
Thanks, Sergio. I need to study your script a bit, but it showed me what I did wrong the first go around. I was extracting the coordinates, but all I needed was the node_id. Plus the syntax on writing the list.
Here's version 2. Not robust enou…
Say, that's a clever trick @disla! Collapsing a shell's edge into it's opposite side -- I've missed that one along the way. Emphasis for the "Create New Component" step in the process that makes the new Line elements around top perimeter (nice set…
I mean when I'm Copying/Moving parts while building an assembly. Ex.: Laying out a steel staircase, on slope, with shells. Main Stringer meshed with Mecway Auto2D. Multiple step support angles, crossmembers, guardposts, etc., along its slope. Co…
I'm often wishing the Move/Copy dialog box had the section FROM (node) ==> TO (node). Would save me a lot of cut&paste from the distance dialog box. Added bonus if it were GUI pickable.
That said, I am otherwise rather enjoying version 15.
Hmmmm. Aspect ratio of triangles look a little sharp, but results were comparable to a full quadrilateral model.
When modeling shells, I try and use the largest element size possible, then refine from there.
Only know of creating a Named Selection for the first windowed group, then adding nodes (faces, elements) for the subsequent groups. I often have several Named Selections running to perform Adds or Subtracts and arrive at what I want.
